Aceclofenac

Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) analog of Diclofenac. It is used for the relief of pain and inflammation in rheumatoid arthritis, osteoarthritis and ankylosing spondylitis. (In Vitro) :Aceclofenac (1-30 μM; 72 hours) significantly decreases interleukin-6 production and fully blocks prostaglandin E2 synthesis by IL-1β- or LPS-stimulated human chondrocytes.Aceclofenac inhibits COX-1 with IC50 values superior to 100 μM, but decreases by 50% COX-2 activity at the concentration of 0.77 μM in the whole blood test.Aceclofenac increases the synthesis of interleukin 1 receptor antagonist and decreases the production of nitric oxide in human articular chondrocytes. (In Vivo) :Aceclofenac exhibits Cmax (4.59 μg/mL) following oral administration (rat 20 mg/kg) .Aceclofenac exhibits terminal elimination half-life (rat 3.24 h) due to high plasma clearance (rat 1.10 L/h/kg) following intravenous injection (rat 10 mg/kg) .
